이 기사의 예에서는 jQuery가 점진적인 표시 효과를 사용하여 문자의 다단계 관계 다이어그램을 구현하는 방법을 설명합니다. 참고할 수 있도록 모든 사람과 공유하세요. 세부 내용은 다음과 같습니다.
다음은 jQuery가 페이드 아웃 효과를 사용하여 캐릭터의 다단계 관계 다이어그램을 구현하는 방법을 보여줍니다. setQuestPose:function의 n은 객체의 총 수를 나타내고, r은 경계를 나타내고, i는 객체의 수를 나타냅니다. , w는 외부 물체의 광대역을 나타내고, h는 외부 물체를 나타냅니다. 높이 d는 실제 각도를 나타냅니다. 오른쪽 하단에 오류가 있는 경우 페이지를 새로 고치십시오.
런닝 효과 스크린샷은 다음과 같습니다.
온라인 데모 주소는 다음과 같습니다.
